It is a true struggle to get my feet into these. I bought size 12, and you would think they'd scale up the opening for larger foot sizes, but no. I feel like I'm going to rip the tag off every time I have to stretch them out to get them on. So far they have held up. (Tip: start with your foot sideways, then rotate the shoe once you get it in halfway to the heel.) That said, these shoes are beautiful and comfortable (once you get them on). They're warm, and they perform well on the snow (after waterproofing).
